I did read it. I am still confused as to why my rig works when many others like it don't. I was more asking you, since you seem to have an understanding of the issue beyond my own, if you have any insight on why.

You are running the game on Mac that is why. Some systems are build better than others and Macs are configured better majority of Windows running computers, so it is not a surprise that less Mac users encounter problems with games such as SWTOR which requires ridiculous amount of memory and RAM to run properly.

This is true of all software in general. Not just gaming, but virtually the entire software industry has been extraordinarily slow to adopt x64. Hopefully with the EoS (end of support) of Windows XP and the prevalence of consumer-grade desktops with 4GB+ of RAM we might actually see some advancement.
